This only changes behavior for the tsd_generic path, where pthread_getspecific() can report no TSD after the pthread key destructor has finished. Other TSD backends keep tsd_teardown_done() as a constant false, so the added checks compile out there. Avoid recreating TSD for late deallocations. Preserve existing reincarnation behavior for late allocations and nonzero reallocations. Add Linux CI coverage for force_tls=0, with and without --enable-debug, to exercise the Android-equivalent generic TSD path.
